North Korean dictator Kim Jong-un has warned that his country must be more ready for war now than ever before in the latest escalation of aggressive rhetoric from the communist regime . It follows the test launch of an advanced type of intermediate-range ballistic missile earlier this month. In January, North Korea abandoned its policy of reunification with the South, labelling it as the principle enemy, and abolishing government agencies responsible for cooperation. But in the Korean diaspora in Australia, hopes of peace and unity live on. Defectors and their families have come together for a rare meeting with South Korean migrants, to strengthen ties outside the Korean Peninsula.
